Description

Wireless broadcasting system and speaker control device {WIRELESS BROADCASTING SYSTEM AND DEVICE FOR CONTROLLING SPEAKERS}

The present invention relates to a wireless broadcast system and a speaker control device, and more particularly, to a wireless broadcast system and a speaker control device capable of simplifying a cable connection structure between devices by transmitting broadcast signals and control signals in a wireless communication method.

In general, as shown in FIG. 1, the broadcasting system includes various broadcasting source devices 10, an output amplifier 30, a speaker selector 40, such as a CD player, a tuner, a microphone, a cassette deck, and the like. And a speaker 50 or the like is connected by a cable.

Therefore, the number of cables connecting each device is large, the type of cable is also very diverse according to the type of device, the type of transmission signal, and the like, and the type of connection terminals suitable for device characteristics is inevitably varied. For example, even when only the broadcast source device 10 is connected to the CD player, tuner, microphone, cassette deck, etc. to the audio mixing device 20 at the same time, each connection cable must be provided.

On the other hand, the conventional broadcast system is inconvenient to manually operate each device to control each device, that is, the broadcast source device 10, the audio mixing device 20, the output amplifier 30, the speaker selector 40 and the like. In order to solve the problem, a control cable 21 for controlling other devices in the audio mixing device 20 is separately connected. In this case, there has been a problem that the cable between devices increases, and the configuration becomes more complicated.

In addition, in order to connect the devices, the operation of binding the connection terminals located at the end of the cable to each device must be performed in advance. Therefore, the operation of binding or removing the connection terminals takes considerable time and the number of connection terminals. The more, the more complicated the later management.

Moreover, the biggest cause of problems in the broadcasting system is not the problem of the device itself, but rather a problem such as a disconnection of the cables connecting the devices with each other, or a breakdown or removal of the connection terminals. It may cause a broadcasting accident.

In particular, if the broadcast system is configured to be mobile or if there is a mobile device in the broadcast system, the cable for connecting the device must also be moved along with the movement. In this process, the cable and the connection terminal are broken, so that the broadcast itself is impossible. It occurs frequently.

And even if the administrator recognizes the occurrence of a broadcast accident, it is difficult to determine which part of the cable or connection terminal has a problem.

In addition, the analog signal has a lot of effects on the broadcast sound quality or image quality depending on the state of the signal transmission cable, when the broadcast using the analog signal, the degradation of the broadcast sound quality and image quality due to aging of the cable or connection terminal There is a hassle of having to replace cables and connections on a regular basis to prevent.

In addition, in the case of constructing a plurality of local broadcasting apparatuses in a building or the like, a conventional broadcasting system connects a local broadcasting apparatus to an audio mixing apparatus of a main broadcasting apparatus, and transmits a broadcast signal from the main broadcasting apparatus to each local broadcasting apparatus. There is a disadvantage that a separate broadcast cable must be installed in order to transmit.

Meanwhile, in the conventional broadcasting system, the speaker selector 40 simply uses a structure such as a switch to determine which speaker 50 the broadcast transmitted through the audio mixing device 20 and the output amplifier 30 will be output through. It is a device to select.

Since the speaker selector 40 connects the output amplifier 30 and the speaker 50 in a 1: 1 manner so that a broadcast is output, when a broadcast is output through a plurality of speaker channels, for example, when an eight-won broadcast is required. An eight-line (16-line) cable must be connected between the output amplifier 30 and a plurality of cables, such as a separate control cable or a power supply cable, must be installed in the speaker selector 40. Therefore, the conventional speaker selector 40 has a limitation in plural broadcasting.

In addition, since the function of the conventional speaker selector 40 is limited to simply selecting the speaker 50 as described above, there is a problem that the output amplifier 30 must be provided separately from the speaker selector 40. .
